Bug Fix: add command handling for '--version' & '-v'

[lsqproduction]

This addresses #5106 . Added handling for -v and --version in getCommand(), so it will work both inside and outside of the console.

Turn off Yargs' default behavior for --version in prepareOptions() so our logic to display version info will kick in.

let me clean up the commits

I'm not too concerned about you messing with the commits. I can see the history of changes made easily enough since there aren't too many.

cleaned up the commits anyways :-) good to practice my rebasing.
